The vehicle acceptance team for Gemini launch vehicle (GLV) 1 inspected the vehicle and reviewed its manufacturing and testing history, focusing on the results of the Combined Systems Acceptance Test (CSAT) of September 6.

The team found GLV-1 to be unacceptable, primarily because of severely contaminated electrical connectors. In addition, the qualification of a number of major components had not been properly documented. Between September 21 and 29, Martin engineers inspected all of the 350 electrical connectors on GLV-1 for contamination and found 180 requiring cleaning or replacement. All electrical connectors on GLV-2 were also reinspected and cleaned or replaced as needed. This extensive inspection invalidated much previous testing, requiring sub-system tests and CSAT to be rerun. Preliminary CSAT was completed October 2, final CSAT October 4.
